ROLLER DlEFOR MAKING lvlETALLlC LATHENG.

SPECIFICATION forming part of Letters Patent No. 604,695, dated May 24,1898.

Application filed. June 29, 1897. Serial No. 642,804. [No model.)

To all whom it may concern: Be it known that I, ALEXANDER R. Fon- DYOE,a citizen of the United States, residing at Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Roller-Dies for Making Metallic Lathing, of which thefollowing is a full, clear, and exact description, such as will enablethose skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification. The invention relates to improvements inrollerdies for making metallic lathing, and r 5 more particularly tosuch devices for making the lathing disclosed in an application filed byme on the 5th day of April, 1897, and having Serial No. 630,680. Thelathing disclosed in said application consists, primarily,of a metallicplate having apertures formed therein, the metal displaced by theformation of said apertures turned back to form flanges, the saidflanges arranged in rows projecting alternately from opposite sides ofthe plate, and also arranged so that the flanges of one row break jointwith the flanges of an adjacent row.

The invention in the present instance has for its object theconstruction of roller-dies 0 adapted to transform a sheet of metalpassed between the same into the lathing disclosed in said application.

The invention consists, primarily, of two rolls, each of which isprovided with annular 3 5 rows of male dies projecting from itsperiphery and annular rows of female dies extending into its periphery,the said rows of male and female dies being arranged to alternate witheach other and so that the male dies of 0 one row break joint with thefemale dies of an adjacent row, and the said rolls being so mounted thattheir relative positions will be such that the male dies of one rollwill register with the female dies of the other roll.

The invention also consists in providing each of the rolls with annularogee formations. The latter are so arranged that they alternate with therows of male and female dies, By

means of these ogee formations the lathing may be corrugated or beadedbetween the keys, as shown in the said application.

The invention further consists in the novel construction, combination,and arrangement of parts, such as will be hereinafter fully described,pointed out in the appended claims, and illustrated in the accompanyingdrawmgs.

In the accompanying drawings, in which similar letters of referencedesignate corresponding parts, Figure 1 is a sectional view of theroller-dies embodying the invention on the line 1 1 of Fig. 2. Fig. 2 isa sectional View on the line 2 2 of Fig. 1. Fig. 3 is a side elevationof one of the corrugating-disks. Fig. 4 is an edge view of the same.Fig. 5 is an end elevation of the roller-dies. Fig. 6 is a frontelevation of the same. Fig. 7 is a plan View of a section of lathingsuch as is made by the roller-dies. Fig. 8 is a sectional view on theline 8 8 of Fig. 7. Fig. 9 is a similar View on line 9 9 of Fig. 7.

Referring to the drawings by letter, A A designate the roller dies. Theymay be mounted in a machine having any construction suitable in thepremises provided with mechanism for driving the rolls at the same rateof speed. Asboth rolls are exactly alike,

a description of one will suffice for both.

On the supportingshaft B are mounted disks of three differentformations. One set, formed of the disks O, carry the male dies, whichserve to slit or cut the metal and to turn back the edges of said slitsto form keys. Another set, formed of the disks D, serve to formcorrugations or beads in the metal plate. These corrugations divide theplate into panels and also strengthen the said plate against certainstrains. The set formed of the disks E carry the female dies, whichcooperate with the male dies to form the flanges and keys.

As all the disks 0 are exactly alike, a description of one will besufficient for the rest of the set. The disk 0 has projecting from itsperiphery at regular intervals the male dies 0. Each of the latter hasan elongated 5 cutting edge 0 toward which the sides of the die slopefrom the comparatively broad base 0 The cutting edges 0 c aresubstantially concentric with the disk. The corners of each, as at 0 arecut away to insure a gradual and easy entrance and exit of the die intoand from the metal. If these corners should not be cut away and the diehave an abrupt entrance and exit, the metal would be torn and distorted.

As all of the corrugating or beading disks are exactly alike, only oneneed be described. The periphery of the disk D has an ogee formationextending around the same, which, with another disk having a similarformation on its periphery, corrugates or beads the plate. The disksalso serve to guide the plate as it passes between the rolls and tend toprevent a movement of the same to the side. The disks E E are alsoalike. In the periphery of the disk E the female dies 6 e are formed.The latter are substantially of the same shape as the male dies of thedisk G and arranged at like intervals. The male die a is of suchdimensions as to register with the male die 0, and preferably it is madelarger, so that considerable space will intervene between the walls ofthe same and the male die when the two are in mesh. This interveningspace allows sheets of metal of different thicknesses to be operatedupon and also allows the flanges to assume the irregular form, as shownin the before-mentioned application. The shape of the male and femaledies is such that the flanges formed by them will be inclined towardeach other to form a key.

The disks are splined on the shaft B, so as to be immovable relativethereto. To insure their solidity, they may be secured one to another inany suitable manner. Clampingplates may also be placed on the shaftoutside of the disks to force the latter together.

The relative arrangement of the disks 0 and E is such that the male diesof the former break joint with the female dies of the latter. Betweenthe two the corrugating or beading disk D is mounted. I11 someinstances, however, it may be desired to make a lathing without thecorrugations or beads. This can be done by leaving out the corrugatingor beading disk.

The relative arrangement of the rolls is such that when placed in anoperative position the male dies of one roll register with the femaledies of the other roll and the corrugating-disks of both rolls register.

While the hereinbefore-described embodiment of the invention is thepreferred one, yet it can be departed from to a considerable extentwithout departing from the spirit of the invention. For instance, eachroll may be made of a solid cylindrical piece of metal, with the severalforming devices cast or cut in the periphery of the same. Then again, itcan be formed of a hollow cylinde also,

the male dies may be made separate and mounted on the cylinder in anysuitable manner. Other changes are also obvious.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a roller-die for making metallic lathing, a roll having an annularrow of female dies extending into its periphery, and an annular row ofmale dies projecting from the periphery of said roll, the said male andfemale dies being separated from each other and their relativearrangement being such that those forming the row of male dies breakjoint with those forming the row of female dies.

2. In a roller-die for making metallic lathing, a roll having an annularrow of female dies extending into its periphery, an annular row of maledies projecting from the periphery of said roll, the said male andfemale dies being separated from each other and their relativearrangement such that those forming the row of male dies break jointwith those forming the row of female dies, and the said roll having anannular ogee formation interposed between the roW of male dies and therow of female dies.

3. In a roller-die for making metallic lathing, the combination of adisk having an annular row of male dies projecting from its periphery, adisk having an annular row of female dies extending into its periphery,the said disks being arranged so that the male dies are separate fromand break joint with the female dies, and means for securing the saiddisks in their proper relative positions.

4. In a roller-die for making metallic lathing, the combination of adisk having an annular row of male dies projecting from its periphery, adisk having an annular row of female dies extending into its periphery,a disk having an annular ogee formation extending around its periphery,the said disks being arranged so that the male dies are separate fromand break joint with the female dies and so that the disk having theogee formationis interposed between the disk having the male dies andthe disk having the female dies, and means for securing said disks intheir proper relative positions.

5. In a roller-die for making metallic lathing, a roll having an annularrow of female dies consisting of apertures extending into the peripheryof said roll, and the said roll having an annular row of male diesprojecting from its periphery, each of said male dies having a cuttingedge substantially concentric with the axis of the roll and with thecorners of said edge cut away to permit a gradual entrance and exit ofthe die into and from the metal on which it operates, the said diesbeing arranged so that the male dies of one row are separate from andbreak joint with the female dies of an adjacent row.

6. In a roller-die for making metallic lathing, a roll having an annularrow of female dies consisting of apertures extending into the peripheryof said roll, each of said female dies having its interior wallsinclined to approach each other as they extend inwardly, and the saidroll having an annular row of male dies projecting from its periphery,each of said male dies having a cutting edge substantially concentricwith the 'axis of the roll and with the corners of said edge cut away topermit a gradual entrance and exit of the die into and from the metal onwhich it operates, the said dies being so arranged that the male dies ofone row are separate from and break joint with the female dies of anadjacent row, and the relative dimensions of a male and a female diebeing such that the male die is smaller than the female die so that whenthe male die of one roll registers with the female die of another rollconsiderable space between the same will exist to permit the metal upsetbetween them to assume the form of an irregular collar to constitute akey.

7. In a machine for making metallic lathing, the combination with a rollhaving a series of disks provided one with a series of cutters, anotherwith a series of depressions, and an intermediate disk; of a cooperatingroll also havinga series of disks provided one with a series of cutters,another with a series of depressions and an intermediate disk, thedepressions in each roll being directly opposite the cutters in theother roll.

In testimony whereof I hereunto affiX my signature in the presence oftwo witnesses.
